Suppose there is a bag containing 20 white marbles (upper w), 20 red marbles (upper r), 20 yellow marbles (upper y), and 20 green marbles (upper g). someone mixes the marbles thoroughly, draws one marble at random, puts the marble back in the bag, mixes the bag thoroughly, and draws another marble at random. complete parts (a) and (b) below.
a. list all possible outcomes of this process. choose the correct answer below.

The total possible outcomes are

WW, RR, YY, GG. WR, WY, WG. GW, GR,GY, RW, RY,RG, YW, YR,YG

Step-by-step explanation:

Given

20 White Marbles

20 Red Marbles

20 Yellow Marbles

20 Green Marbles

Event that someone picks 2 marbles (1 at a time) with replacement

Required

List all possible outcomes of this process

Follow the steps below:

Step 1: Provided that the person replaces the marbles after making a selection. The possible outcome is as follows

1. The person picks marble of the same color;

The outcomes are

WW, RR, YY, GG

2. The person did not pick marble of the same color;

This is subdivided to

The person picks the white marble first

WR, WY, WG

The person picks the green marble first

GW, GR,GY

The person picks the red marble first

RW, RY,RG

The person picks the yellow marble first

YW, YR,YG

The total possible outcomes are

WW, RR, YY, GG. WR, WY, WG. GW, GR,GY, RW, RY,RG, YW, YR,YG

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be
